FEED-WATER REGULATOR.

SPECIFICATION forming part of Letters Patent No. 700,449, dated May` 20,V 1902.

Application liled July 1 1901. Serial No. 66,625. (No model.)

The object of this invention is the produc-` tion of a simple, cheap, and sure apparatus which is particularly applicable for 'regulating the feed of water to the boiler of an automobile.

The embodiment of the invention that is illustrated by the accompanying drawings has a pump for forcing water from the supply-` tank to the boiler, with the necessary checlt and relief valves to control the iiow and prevent uudue pressure, and a Heat-valve arranged to admit water when the supply in the boilerV becomes reduced and to stop the feed after a sufficient quantity has been supplied.

Figure l of the views shows a side elevation of the regulator. Fig. 2 shows on larger scale a section of a boiler-tube containing the iioat-valve, and Fig. 3 shows a sectional view of the relief-valve. y

. The pump 4., which is driven by the eccentricy 5, is connected with the supply-tank 6 and the boiler-tube 7. In the connection betweenV the pump and the supply-tank is a clapper check-valve 8, and in the connection between the pump and the boiler-tube are the clapper check-valves 9 and 10. The pipe 11 beyond the check-valve 9 is connected with the supply-tank, and in 4this connection isa relief-valve l2. This relief-valve is provided with a spring 1.3, the tension of which is adj usted by the screw-spindle 14., so that when the pressure in the pipe 11 becomes greater than desired this valve will be forced open audallowthe water being pumped to return4 to the supply-tank. The inlet-pipe 15 extends from the top nearly to the bottom of the boiler-tube 7. The lower end of this pipe is closed by a cap 16 in any suitable manner, and through the side of the pipe is au opening 17. Movable up and down on the pipe 15, so as to cover and uncover the opening, is a tube 18, that extends through the shell 19.

Each end of the tube 18 is threaded and provided with a nut A20 and packing 2l for keep-l ing water out of the float valve, which is formed by the tube and shell; As the water is used for generating steam and the level in the tube becomes lower the iloat drops until the opening 17 is uncovered. Then water will be pumped in until the float rises enough to close the opening and out o thefeed. When the opening is closed and the pump is in operation, the water returns through the reliefvalve to the supply-tank.

The apparatus is very simple in` construction, and it is eective inoperation. The

in its movement by the inlet-tube, and any v jarring of the vehicle upon which the apparatus is mounted does not affect the operation of lthe feed.

Any kind of a pump having suitable capacity may be used with this regulator, which is adapted for supplying water to the ordinary types of boiler.

I claim as my invention- A feed-water system consisting of a vertically-arranged tubular shell, a feed-Water pipe with one end closed and an opening through its side, extending vertically into the shell, a oat'with a central opening, the walls of vwhich opening fit the exterior of the feedwater pipe, that is adapted to move up and down the feed-water pipe so that the walls of its central opening will close and open the opening Y'through the side of the feed-water` pipe, a pump connected with the feed-water pipe, a connectionfrom the feed-water pipe to a supply-tank each side of the pump, a

Fcheck-valve in the feed-waterk pipe eachside of the pump, and `an adjustable relief-valve Alocated in the connection froinfthe feed-water pipe to the supply-tank that is between-theQ pump and-the float-valve shell, substantially as specified.
